内蒙古自治区太阳总辐射的气候学计算及其时空分布特征
The climatological calculation of global solar radiation and its temporal and spatial distribution in Inner Mongolia Autonomous Region
摘要
Abstract
By analyzing and comparing climatological calculation methods of global solar radiation at home and a-broad,an optimal calculation formula was identified and then used in Inner Mongolia.In accordance with monthly global solar radiation and percentage of sunshine at 24 solar radiation observation stations in Inner Mongolia and its surrounding areas,experiential coefficients in the formula were fitted in terms of least square method.An interpola-tion method of IDW was then used to extend these coefficients to 108 weather stations.Finally,a global solar radia-tion calculation model was established for Inner Mongolia.The calculating results from this model show that the annual global solar radiation is in a decreasing trend from 1978 to 2010,while it is not significant and the decrea-sing rates in different regions differ obviously.The highest value of global solar radiation occurs in May,then fol-lows in June and July,and the lowest value is in December.The monthly variation presents a single peak.The spa-tial distributions of monthly global solar radiation are consistent with that of annual global solar radiation,and both increase gradually from northeast to southwest of Inner Mongolia.The annual global solar radiation ranges from 4633 MJ·m -2 to 6616 MJ·m -2 .The grade of solar energy resources in Inner Mongolia is abundance grade or a-bove it.The grades of solar energy resources fall in categories of the best abundance grade and better abundance grade in most areas of Inner Mongolia,so it has great potential for development and utilization of solar energy re-sources.关键词
